After you installing your own git server (http://hobby.keluargareski.net/2012/02/11/how-to-install-git-on-centos-5-6/), dont forget to create your first step for GIT repository
On Remote Sides
mkdir my_project.git
cd my_project.git
git --bare init
On Client Sides
mkdir my_project
cd my_project
touch .gitignore
git init
git add .
git commit -m "Initial commit"
git remote add origin youruser@yourserver.com:/path/to/my_project.git
